This injection molded, rigid plastic prototype device -- which you assemble from our kit -- attaches to your smartphone or smartphone case with adhesive, and is perfect for taking outside for in-the-field measurements of different materials. Follow the included instructions (and/or 3d print your own from the plans provided there) and scan liquids, gases, or lights using the free, open source web-based software at SpectralWorkbench.org.
Spectrometry is a powerful technique for analyzing materials, and our open community of DIY environmental researchers has collaborated since 2010 to design, improve, and refine these affordable tools. Build one yourself and join us today!
Compared to the papercraft Foldable Mini-Spectrometer, this kit offers a much higher precision, more field-ready ruggedness, and a strong frame to attach extensions and expansions, which will be shared on the PublicLab.org website. While the mobile interface is not yet as robust as the desktop edition, you can still do most of your analysis on the desktop after capture!
The Smartphone Spectrometer fits most smartphones, including Android and iOS devices; by adhering to the back of your phone with removable adhesive, or better yet, permanently attaching to a phone case. On Chrome and Opera for Android, you can do "live mode" using the live video feed from your phone's camera. While iOS does not yet have support for the HTML5 webcam API, iPhones and many other phones can be used to photograph spectra (which is higher resolution than live video) for upload and analysis.
For a more robust, less compact tool, try the $40 Desktop Spectrometry Kit, which plugs into your computer with a USB cable, or for a more affordable tool, the $10 papercraft Foldable Mini-Spectrometer.
